PHILIP HAcKLER, on MINNEAPOLIS, MINNESOTA.

LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 337,396, dated March 9.1886.

Application filed July 22, 1885. Serial No. 172,337. (No model.)

To aZZ whom it may concern/.-

Be it known that I, PHILIP HACIILER, a citizen of the United States, anda resident of Minneapolis, in the county of Hennepin and State ofMinnesota, haveinvented certain IInprovements in Lubricators, of whichthe following is a specication.

My invention relates particularly to improvements in lubricatorsdesigned for use with thelower roll or shaft of a grain-elevator. Theserolls are located at the lower end of an elevator-leg, in what is knownas the elevator-boot, and in a position that is not easily accessible,so that it is inconvenient to use any of the common forms of lubricatorsfor lubricating this shaft.

My invention consists in the construction and combination of deviceshereinafter described, and particularly pointed out in the claim.

In the drawings forming part of this specication, Figure l is a sideelevation of an elevator-leg having my improved lubricator appliedthereto. Fig. 2 is a vertical cross-section ofthe shaft and lubrioator.

In the drawings, H, Fig. l, represents the frame of an elevator-leg. l Iis the belt, and J the boot. The shaft A is the lower shaft or roll ofthe elevator, and it is located in the boot J. The shaft A is journaledin the box B. The upper box, B, is provided with an inclined holethrough it radial with` the shaft A. Into this hole is tted a pipe, C.This pipe is of cast-iron, usually a piece of threequarter-inch gas-pipeabout twenty-six inches long. The upper end of the pipe is screwthreadedat c, and a threaded cap, D, is tted thereon. This cap is provided withthe small hole d, extending through it.

Within the pipe C,and bearing on the shaft A, is the cylinder or roll ofgrease G. This roll is preferably composed ot' the following ingredientsin substantially the proportions specified: beeswax, three-quarters ofapound; paraftine, one pound; graphite, three ounces; castor-oil, onepint; and in cold weather I prefer to add crude oil, one pint. Thiscompound is made into a roll or cylinder that is a little less indiameter than the inside of the pipe, so that it moves freely therein.

E is a plunger or follower, of metal, that has an eye, e, into which thewire F is secured by an eye, f. The wire F extends through the hole d inthe cap D, and-is provided at its upper end with the ring f. The wire Fand the follower E are together about two inches shorter than the pipeC, so that when the'ringf strikes on the cap D the. lower end of thefollower is at about that distance from the shaft. It is thereforeimpossible for the follower at any time to come in contact with theshaft. When the ring comes in contact with the cap, it will indicate tothe workman or operative that the grease is nearly all eX- hausted, andthat a new supply isrequired; but should this be neglected the contactof the ring with the cap will keep the follower from coming in contactwith and wearing the shaft. When used in other locations, the pipe maybe in an upright position. In either case the weight of the metalplunger prevents the pushing ofthe grease up in the pipe, and when thelpipe is inclined this result is secured while a part of the weight ofthe plunger is borne by the wall of the pipe.

I claim as lny invention- The combination of the elevator-boot J, shaftA in the lower part thereof, box B, surrounding said shaft, and formedwith au inclined hole through it radial to shaft A, the inclined pipe C,having its lower end fitted in the inclined hole of the box, thefollower E, fitting in said pipe, and having eye e, the wire F, havingring f/, engaging with eye-e, the cap D, and the roll of grease G, allsubstantially as described.
